IMPROVEMENT IN AUTOMATIC CLOSING BUNGS AND FAUCETS.

Specication forming part of Letters Patent No. 157,092, dated November24, 1874; application filed October 17, 1874.

To all whom t may concern:

Be it known that we, LEVI DAROZIR and LEANDRE BOUDREAU, both of the cityand county of Worcester and Commonwealth of Massachusetts, have inventedcertain new and useful Improvements in Automatic Closing Head-Bangs forBeer and other Barrels; and we do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings forming a part of this specification, and inwhich- Figure l represents a longitudinal central section through one ofour improved headbungs when applied to use in a barrel, a section of thebarrel-head being shown. Fig. 2 represents a similar section after thefaucet has been introduced into our improved headbung for the purpose ofdrawing beer or its contents from a barrel, only a section of the faucetbeing shown. Fig. 3 represents a side -view of our improved head-bungdetached.

Fig. 4 represents an end view of the spring head-plate, and Fig. 5represents a side view of the piston-key.

To enable those skilled in the art to which our invention belongs tomake and use the outer shell or case of the bung, having a flange,

B, upon its front end, said shell or case A being made slightly taperingfrom its inner end C to the flange B. Within the interior of the frontpart is arranged a conical packing-ring, D, which we prefer to make ofcork, but it may be made of rubber or other suitable elastic material.This ring is forced in from the front end and compressed during theoperation, so that after it has passed the front iiange a it will expandand make a tight joint between its outer surface and the conical surfaceof the chamber in the front end of shell A, and between its front andrear edge and the flanges a and b, which project in from the innersurface of shell A. E is a closing valve, fitted to work in a conicalchamber in the rear end of shell or case A, the cone shape of saidchamber being the reverse of the one in the front end of the shell A.The valve E, in this instance, is made of cork, but it may be made ofany other suitable. material, and it is made cone shape, to lit thecone-shaped chamber, in which it is arranged. F is a metallic head, uponits rear end having a spindle, G, which passes through the valve, and isprovided with a metal screw-cap, H, provided with key-holes c c, bywhich said cap can be screwed down to expand valve E, as occasion mayrequire, to cause it to properlyflt and tightly close the chamber whenit is in the position shown in Fig. 1. I is a key, having forks d d, toenter the holes c c in cap H, and by which said cap can be screwed downvery quickly by the operator, the spindle of key I being insertedthrough the open hole J in the front end of the bung before the spindleK of the faucet is driven in. In rear of head F is arranged acone-shaped spiral spring, L, with its point resting against headF,while its larger end rests against the inner end of head-plate M, theouter end of said head-plate being held within the rear end of the shellor case A by means of pins or screws c e. Head-plate M is provided witha series of holes, f, and the inner end of shell A is also provided withholes g. The interior of shell A is chambered out more in that part inwhich spring L is arranged, asA shown at h, Figs. l and 2. A groove, m,is formed upon the interior of shell A, between flanges b and theconical chamber in which piston E works.

In applying our improved bung to the heads of barrels, a conical hole isfirst bored in the head N, and also a groove, n, cut in the head outsideof the hole, so that, when the'shell or case A is driven. into the headN of the barrel, it will make a tight joint, as indicated in Figs. l and2- of the drawings. Screw-holes may also be made in the flange B, forscrewing the iiange to the head'of the barrel. By having the groove marranged between the reverse chamber, the liquid has a free escape assoon as the valve is started back, even though the front end of valve Eshould reach beyond said groove. The pressure of the beer or otherliquid in the barrel, if considerable, against valve E would cause it tofit tightly, even though sprin g L were not used; but there would be aliability, in such case, of more or less waste of liquid than there iswhen a spring, L, is used therefore, we prefer to use a spring, L, orequivalent device, in all cases. When beer or other liquid is to bedrawn from the barrel the end K of the faucet is driven into the bung sothat its rear end Will strike against cap H and drive valve E back, asindicated in Fig. 2 of the drawings, and when in this position the endof the faucet will be held rmly and tightly Within the elastic ring D,of cork or other suitable material, so that no liquid can escape exceptthrough the faucet, which it can do freely as soon as the faucet stopperis turned, since there is an open space, o, between the outer surface ofvalve E and its chamber, when driven back by the end of the faucet, asshown in Fig. 2, the liquid passing freely through said space, and alsothrough openings 2 2 in the end of the faucet. As soon as the faucet isremoved spring L instantly forces valve E forward and prevents anyfurther escape of the liquid.

It will thus be seen that our improved bung is very con venient andsecure. It enables the dealer to test the beer without Wasting but verylittle, and when all the beer has been drawn and the faucet removedvalve E is automatically closed, thus keeping the barrel closed.

Having described our improvements in automatic closing head-bungs forbeer and other barrels, what we claim therein as new and of ourinvention, and desire to secure by Letters Patent, is

l. The combination, with shell or case A, of packing-ring D, valve E,and spring L, substantially as and for the purposes set forth.

2. The combination, with the front outer end of case A, provided withflanges a and b, of elastic packing-ring D, substantially as and for thepurposes set forth.

3. The combination, with shell A, provided with reverse conical chamber,as described, of conical ring D, and conical valve E, substantially asand for the purposes set forth.

4. The combination, with shell or case A, and valve E, of the perforatedremovable head-plate M, and spring L interposed between said valve andhcadplate, substantially as and for the purposes set forth. Y
